Title: Video output circuit
Inventor: MAYAMA ICHIRO
IPC: G11B19/00
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To provide the video output circuit that is operated at a low power supply voltage. SOLUTION: The video output circuit is provided with a voltage/current conversion section 4 that converts a voltage change in a video signal supplied from a video signal source 1 into a current change, a circuit amplifier section 5 that amplifies a level of the video signal converted into the circuit change by the voltage/current conversion section 4 in an output enabled way, and a load resistor 7 that receives an output of the current amplifier section 5 across a voltage of which is outputted externally. Since the video signal is outputted as a current change, an operating voltage Ve of a circuit power supply 8 in the video output circuit is decreased to be a low voltage (2V).  Furthermore, since a boosting power supply circuit in a device using a battery for a power supply is not required, the circuit of the circuit of the power supply 8 is simplified, resulting that the cost is reduced.

Abstract: PURPOSE:To set optionally the original point of the data writing area of a frame memory by using a means to set the horizontal and vertical data write starting points of the data writing areas of the longitudinal and lateral frame memories in a print area to each designated address. CONSTITUTION:The signal designating the writing end point (gh) of the X direction shown as an X end address is previously supplied to the comparator 9 of a control part 3 from a CPU via a latch 11. This designating signal is latched by the latch 11 and inputted to the comparator 9.
